Re: Nav apps for android phones?

Since the original info on this thread is year's old, we might as well update.

I've been using Navionics Marine US West on my android phones, and aside from lacking a night time mode for retaining night vision, it's pretty handy and full featured. All map data is stored locally on the device so you don't need a data connection if you are away from land. I've been waiting for this app to become available on my Nexus 7, but the developers seems to be dragging their feet.

I'm going to have to check out mobileGRIB and Pocket Grib.

I had another app that let you plot your anchor position and scope, and it would alert you if you started dragging. I forgot what it was called, but made sleeping on the hook a little easier.

Just a heads up that PocketGrib is now available on Android (as well as iOS) with very similar functionality to the iOS version. You can find it in the Google Play store.

Cheers,

Re: Nav apps for android phones?

I have just downloaded this app on my I PAD and it seems to be as advertised initially with updates within 2 minutes on all boats positions (it tells you the time since the last update and most are within 30 seconds)

I contacted the OP and asked about the updating and his reply-

Quote:

The majority of our feeds are direct in real time from the AIS Receivers (over 70%). Our servers are handling over 20MB/s of data arriving. For instance in the UK around the Isle of Wight we get updates from the fast ferries every 2s and their updates appear in Boat Beacon within a second of being received.

All the other data is accurately time stamped at source and collated over 1 minute. On average this is only 30s behind real time and is displayed with the corrected time (and interpolated position) in Boat Beacon. You also have to remember that AIS transmissions from ships are sent at varying intervals from once every 3 minutes to every 2s depending on their status and speed. So for example a ship at Anchor can show a status that is 3 to 4 minutes old. Also the transmissions are not guaranteed and can be easily blocked by passing ships, bridges and island's etc.Rorythepilot

I will test against the AIS on the boat when I get down to it.

Good show,

Re: Nav apps for android phones?

Hi,

I wrote and use Boat Beacon - Marine AIS Navigation, based on my own needs sailing in the Bristol Channel. It plots your own boat's position and receives other ship positions via AIS in real time and , unlike other apps, I mean real time, down to the second. I have just completed and released the Android version.

It also provides continuous collision detection out to 30 miles and can share your position too so other Boat Beacon users can see you and if you have an MMSI you can also appear on Global AIS systems like Marine Traffic, ShipFinder, AIS-Hub and Vessel Tracker etc. You can find it in the Play Store or visit the web site boatbeaconapp.com

It is not a substitute for real AIS and relies on a mobile data connection - so can only be used around Coastal and Inland waters.

I have 3 free copies to give away to the first 3 folks who PM me.

I am considering purchasing Navionics for my Dell Streak which is currently running Android 2.2. Can anyone comment on how they like the software?
Also when it's running is it using up data or just utilizing the built in GPS in the phone?

Gribs

Then Navionics app has the ability to download and overlay the gribs too.

yes, there is plenty of information on their website. mobilegrib dot com.

You can watch a demo video there and see it in action.

This is the info from the website:

mobileGRIB is a GRIB2 viewer for Android. It enables sailors and hobby meteorologists to have detailed weather information always available. This is done by downloading GRIB files of any region of interest. Source for the Gridded Binaries is the National Oceanic and Atmospheric Administration (NOAA). Forecast times and variables can be chosen from pressure, wind arrows, temperature, cloud cover, humidity and precipitation for the upcoming 6 days and between a resolution of 1░ x 1░ or, for even more detail, 0.5░ x 0.5░. By selecting only what the user needs, this procedure will keep the size of the downloaded GRIB file low, making it especially convenient for low bandwidth regions covered only by Edge or GPRS networks, or simply regions with low cellular coverage.

A free version of mobileGRIB is available under the name of mobileGRIB light and can be used for evaluation purposes. It is a fully functional version with outdated GRIB files. To receive actual GRIB forecasts, please purchase the full version.

upcoming features:

remember zoom level
choose forecast interval and period before downloading the GRIB file
offline maps for even less data transfers
offline GRIB file browser
GPS positioning and track
Latitude and Longitude lines
L and H signs for pressure
Isotherms to determine cold and hot fronts and resulting occlusions
weather animation
language support for up to 9 languages

update on old thread.. It never ceases to amaze me that people who claim technical experience can be in error so much. And more amazing that they will put it in a public forum. ie java vs C.. Just because one knew the limits of the JIT version does not mean they understand the realtime capabilities of advance compiled code. If your old enough you would have used interpreted BASIC and thought it would never be fast.. but Visual BASIC and other compiled versions have proven very capable. Of couse It is 2011 and things changed. there are more nav apps for the I-phone but the Droid phones have some of the same and the GPS is as good as any standard one and the I-phone as it uses the same technology..
